A registered sex offender was arrested Thursday on charges of conspiring to commit a homicide after authorities said he hired someone while being held at the Merrimack County House of Corrections in Boscawen.

Authorities wouldn't disclose what Schultz offered in exchange for the killing. Investigators asked for arrest affidavits to be sealed until August to protect the investigation.

Schultz was charged with a Class A Felony and held on $250,000 cash bail after a probable cause hearing on May 14. He is currently being held at the New Hampshire State Prison for Men in Concord.

He is currently serving a sentence of 12 months in jail with three months suspended to be followed by two years probation on charges of failure to register as a sex offender, according to a prison official.
